Did you install either the dkms-Nvidia-package or the proprietary Nvidia driver package? Shouldn't matter anyway, as both install a "Nvidia X Server settings"-applet. With this you can change resolutions, scan frequencies and whatnot. Dangerous? Well, yes. If you set too high a frequency you might damage the monitor. For flatscreens the most common frequency is 50 (older standard IIRC) or 60Hz (most common nowadays). CRT's can vary between 60 to 120Hz. Most common AFAICT is the 75-85Hz range. Your flickering thing might also be because of a too high set screen resolution. Start with 1024x768 and 75ish Hz and go up stepwise. See if it gets better. -- /Sorin -------------- next part -------------- A non-text attachment was scrubbed...
